Roof edge protection for flat roofs: Systems, standards and buying guide

Flat roofs are accessed more frequently than ever before – for PV maintenance, air conditioning, inspection or renovation. The risk of falling at the roof edge is particularly high. A professionally installed roof edge protection reliably protects and is standardized according to DIN EN 13374. This guide will help you find the right system for your flat roof.

Why flat roofs have special requirements

Unlike pitched roofs, the entire roof area of a flat roof is accessible – and therefore potentially dangerous. There is no natural boundary to warn of the edge. In addition, there are smooth surfaces, gravel or roofing membranes that can be slippery. According to DGUV rules, the danger zone begins 2 meters from the roof edge.

Types of roof edge protection for flat roofs

1. Freestanding railing systems with ballast

These systems are installed without penetrating the roof and are ballasted with concrete weights. They are ideal for temporary work and protect the roof waterproofing. Installation takes only a few hours, depending on the roof length.

2. Parapet clamping systems

Clamping systems attach to the parapet and also do not require penetration of the roof membrane. They are particularly stable and suitable for roofs with a parapet height of approx. 15 cm or more.

3. Mobile fall protection systems

For short, one-off deployments, mobile systems are useful. They can be quickly set up, repositioned and transported away – ideal for maintenance teams who visit different properties daily.

Standard Basis: DIN EN 13374

All temporary side protection systems for roofs must comply with DIN EN 13374. This standard distinguishes three protection classes:

• Class A: For surfaces up to 10° inclination – typical for flat roofs
• Class B: For inclinations up to 30° and catch function
• Class C: For steep roofs up to 60° inclination

For flat roofs, Class A is usually sufficient. When purchasing, ensure that the system is explicitly certified according to DIN EN 13374.

Checklist: Finding the right system

• Measure roof length and distance to be secured
• Check parapet height and width
• Consider substrate and roof waterproofing
• Determine duration and frequency of use
• Confirm system certification according to DIN EN 13374
• Observe assembly instructions and manufacturer specifications

FAQ: Roof edge protection flat roof

Do I have to penetrate the roof for railing installation?

Not necessarily. Freestanding systems with ballast do not require roof penetration and protect the waterproofing.

From what parapet height are clamping systems suitable?

Most parapet clamping systems require a minimum parapet height of 15 cm. Exact specifications can be found in the product documentation.

For how many meters of roof length do I need a system?

That depends on the work area. Gerüstexpress will be happy to help you calculate the required system length.
